Summary: An investigation was conducted on a CRDI engine using a blended fuel (WCO20) to explore the impact of fuel injection strategies on engine characteristics. It was found that the use of WCO20 increased fuel consumption and nitrogen oxide emission while decreasing brake thermal efficiency at a base fuel injection pressure of 40 MPa. The physical properties of the WCO20 fuel blend, such as volatility and viscosity, influenced combustion phenomena and reduced engine performance. Increasing fuel injection pressure led to improved combustion characteristics and higher brake thermal efficiency.

Summary: Ethanol-powered spark ignition engines have the potential to mitigate the crisis of fossil fuel depletion and exhaust emissions. However, the promotion of ethanol is hindered by the limitations of the conventional engine design and fuel blend diversity. Flex-fuel engine technology can overcome the fuel flexibility issue and work with a wide range of ethanol blends. This study critically analyzes the technical aspects of flex-fuel engines and evaluates the effects of ethanol blends on engine performance, material compatibility, cold starting characteristics, and unregulated emissions.

Summary: The experimental study evaluates the material compatibility and corrosion characteristics of engine components in methanol-gasoline blends. The results show that increasing the methanol percentage intensifies the corrosiveness of fuel samples and the presence of oxygen in methanol contributes to metal corrosion. The piston exhibits lesser resistance to corrosion compared to the piston ring and valve, and corrosion attack is higher on the engine component surfaces exposed to higher methanol concentrations. Lower methanol concentrations are more suitable for SI engines due to minimal corrosiveness on engine components. Recommendations are provided to enhance the performance of engine components against methanol corrosion.

Summary: Switched reluctance motors (SRM) are attracting attention from the industry due to their simple construction, high reliability, and efficiency. However, controlling SRM is challenging due to its nonlinearities and variable parameters. This study proposes a novel approach combining model-in-loop and hardware-in-loop simulations to control the speed and torque of SRM. The proposed adaptive supervisory self-learning control approach (ASSC) effectively reduces speed variations and exhibits better performance compared to other control approaches. Experimentation confirms the simulation results and demonstrates the improved efficiency of SRM with the recommended ASSC controller.

Summary: In the past decade, there has been a growing interest in studying energy systems for the combined management of power vectors. Most of the published works focus on finding the optimal design and operations of Multi Energy Systems (MES). However, for newcomers to this field, understanding how to achieve the desired optimization details while controlling computational expenses can be challenging and time-consuming. This paper presents a novel approach to analyzing the existing literature on MES, with the aim of guiding practical development of MES optimization. Through the discussion of six case studies, the authors provide a mathematical formulation as a reference for building the model and emphasize the impact of different aspects on the problem nature and solver selection. In addition, the paper also discusses the different approaches used in the literature for incorporating thermal networks and storage in the optimization of multi-energy systems.

Summary: This paper investigates the heat transfer mechanism and factors influencing thermal radiation in the process of supercritical water gasification (SCWG) of coal, and proposes a comprehensive numerical model to simulate the process. Experimental validation results show that thermal radiation accounts for a significant proportion of the total heat exchange in the reactor and a large amount of radiant energy exists in the important spectral range of supercritical water. Enhancing radiative heat transfer can effectively increase the temperature of the reaction medium and the gasification rate.
